and useful Improvements in Transmission Covers for Motor-Vehicles, of'which the fol-. lowing is a specification.

This invention relates to improvements in transmission covers for motorvehicles, and has particular referenceto a deviceto berattached to the cover of a motor vehicle preferably of the Ford type. f

The principal Object of this invention is f to provide an auxiliary hand opening inthe top of ay transmission housing for the purpose of facilitating the rapid adjustment of the transmission bands.

Another object is to produce a device lof this character which maybe attached to theV ordinary Ford transmission housing without altering the construction of the same. A further object is to provide a device of this character which is simple in construction, and therefore cheap to manufacture.

Other objects and advantages'will be-apparent during the 'course of the` following description. Y V r In the accompanying drawings `forming a part of this specification and in which like numerals are employed to vdesignate like Vparts throughout'the same,

Figure 1` is a vertical cross-section of a transmission housing'showing my device ap plied thereto, taken on the line l-1 of Figure 2,

Figure 2 is a topplan view of Figure 1, Figure 3 is a bottom plan view of the housing showing my device attached thereto, Figure 4 is a detail view takenon the4 line 4-4 of Figure 2, and

Figure 5 is a detailfview taken on the line 5 5 of Figure 2. At the present time in order to tighten the transmission bands in a well known make of automobile, it is necessary to remove a number of screws from the cover plate of the transmission housing before the bands can be brought into view for adjustment. It is applicants intention to provide an auxiliary 'coverplate which rmay be quickly removed by the manipulation of a' single thumb nut so that adjusting mecha nism of the bands may he uncovered for adjustment. Y

In the accompanying drawingswherein for the purpose of illustration is shown a preferred embodiment of my invention, the y numeral 5 designates a transmission housing within which are mounted a plurality 4ot transmission bands 6, and 8. `These bands underlie an opening 9k formed in the housing and normally closed vby a cover platekll.vk The cover plate 11 is normally held in place as by screws 12 (see Figure 2). These screwsv have to be'removed in order to expose the 'transmission kmechanism, and accordingly,'I have cut an auxiliary opening 13'in the cover plate 11 and'have provided the same with down-turned lianges 14 and 16. One of these flanges is provided with a downwardly projecting shoulder 17.

In order to close this opening 13, I yhave provided an auxiliary `cover plate 18 which cover plate is held in place by a latching bar 19. This latching bar is carried uponthe end of a screw-thread member 21 passing through the cover `plate 18 and having threaded engagement therewith.

A spring 22 is interposed between the latching har19 and the cover platey 18 and surrounds thescrew-thread member 21. A

21 `when desired.

The manner of operating my device isas A follows :i-

Assuming that the parts are arranged as nut 23 will' cause a loosening of the screw, thus allowing the bar 19 to ymove downwardly and out of engagement with the flanges 14 and 16. As soon as the same has moved va .suiiicientdistance away from the flanges the friction of the spring 22 will cause the locking bar to rotate as indicatedk by the arrows of Figure 8 at which time the auxiliary cover plate 18 may be removed.

In replacing ythe cover plate, the operation wing nut 23 serves to rotate the screw thread 1 shown in Figures land 2, rotation of the is reversed, with'the result'that as the locki ing bar moves through its'arc, one of the ends will come into contact with the shoulder 17 which will 'arrest further rotary movement with the result that the further movement of the screw 21 will merely serve to drawthe locking bar into tighter engagement with the flanges 14C and 16.

It will thus be seen that I have provided a very simple device which through ther manipulation ofone screw will permita person to quickly expose the adjusting nuts of the transmission.

Itis to beunderstood that the form of my invention herewith shown and described is to be taken as aprel'erred example of the saine7 and that various changes in the shape, size and arrangement of parts may be resorted to without departing` from the spirit of the. invention or the ,scope of the subjoined claims. i

IvIaving,l thus described my invention, I claim l. ln a device oli the character described Vthe combination with an automobile having a transmission housing', ot a cover plate positioned thereon and havingl an opening' formed in said cover plate.v an auxiliaryy cover plate Vadapted to close the opening ot said tirst mentioned cover plate, and a pivot.- ed locking; bar secured to said auxiliary plate*y ior the purpose speciied.

2. n a device ol the character described the combination with an automobile having a transmission housing, having' an opening 'formed therein and downturned flanges surroundii'ig the opening, a cover plate adapted to closethe opening in said housing,` and a locking bar pivotally supported by said cover plate and adapted to engage said flanges, tor the purpose specified.

'3. In a device of the character described the combination with an auton'iobile transmission housinghavinga removable cover plate secured thereto, of a n auxiliary cover plate secured to said first mentioned cover plate, said lirst mentioned cover plate have ing; downturn vflanges -iformed therein and having an opening formed therebetween, one Oft said flanges being` provided with a shoulder, a locking bar pivotallv supported beiuath said auxiliaryY cover plate, means lor rotating' said locking bar, a spring' interposed` between said locking` bar and said auxiliary plate and surrounding said bar rotatingl means, said bar being adapted to contact said shoulder, :for the purpose spec itied.

ln testimony whereof I atlix in v signature.
